Osmosis, finally the video documentation

Finally the video documentation for the installation I made with Ewelina Aleksandrowicz and Andrzej Wojtas is online. Thanks to Bernhard Garnicnig and Culture Lab onSite for the support.

:: OSMOSIS ::

A site-specific installation by Ewelina Aleksandrowicz, Alessandro Altavilla, Andrzej Wojtas.

Osmosis is a response to the physical and infrastructural characteristics of 5 Forth Street in Newcastle Upon Tyne, a space carved from one of the main railways bridges of the city.

Osmosis investigates the surfaces of the Culture Lab On Site space as a vehicle for acoustic information, sensed from the outside.
It works as the passage of material from a space with a substantial concentration of sound and events to a dispersed outside.
Osmosis uses the space as a big container of resonance, generated by an horizontal array of 11 piezo speakers placed on the wall, an audio feedback system (2 active speakers, 1 sub, 1 large diaphragm microphone) and 10 window transducers.
The visitors interact with the installation from outside the space, by listening to barely audible sounds and are invited to touch the glass in order to experience tactile sounds emitted by window transducers.

 

The flying ear of invisible architectures

I  will  be part of the festival, Invisible Architecture, with the project “The flying ear”.
Running in Newcastle from the 9th September to 11th (three days), Invisible Architecture is “a micro-festival exploring the invisible yet influential substrates of urban existence”, and it is organised by the artist Will Schrimshaw.

This festival hosts a roster of really interesting artists, some of them Culture Lab based, like the same Will SchrimshawLalya Gaye and our special guest Berit Greinke.
The rest of the line up is just incredible and I am really pleased to take part of this festival:

The Flying Ear leads a remote and detached soundwalk of the streets of Newcastle Upon Tyne. Walkers’ ears are stretched above their heads, elevated to new heights with the help of balloons. Walkers are able to explore vertical acoustic spaces otherwise inacessible to the ear (at least without a ladder).

The Flying Ear, Alessandro Altavilla

It’s tour based and you need to book it if you are interested to take part (please, it would be awesome and the balloons are really nice!). It will run only on saturday 10th September, from 12 to 14.
An article about this event has been publish on the issue of September 2011 of The Wire.

Osmosis

Culture Lab OnSite last July hosted a site-specific sound installation made by Ewelina Aleksandrowicz, Andrzej Wojtas and myself.

osmosis |äzˈmōsis; äs-|

(noun) Biology & Chemistry a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane.

figurative: the process of gradual or unconscious assimilation of ideas, knowledge, etc.: what she knows of the blue-blood set she learned not through birthright, not even through wealth, but through osmosis.

The Quiet Walk, how to compile Pure data with externals, in embedded applications using ofxPD

The implementation of externals has been a real trick.
All the forums seems to deal with people that are advanced programmers, ignoring inexperienced like me.
The information i grasped from spending several hours on forums seems to address to this procedure.

As the externals are not part of the standard distribution of PD vanilla, they need to be compiled on the phone before being usable.
The external should be already available as a .c file to be added in one of the Xcode project folders.
For example, i put my externals in my branch of ofxpd, in order to make them available for other projects.

The file to modify in order to build this external is the main .c of pure data (called m_pd.c) adding the following code at the very end of the file (after void pd_init):

void mess_init(void);

void obj_init(void);

void conf_init(void);

void glob_init(void);

void garray_init(void);

void extras_init(void);

void pd_init(void)

{

mess_init();

obj_init();

conf_init();

glob_init();

garray_init();

extras_init();

}

void extras_init() {

fiddle_tilde_setup(); //fiddle~ is the name of the external

}
